Temperate rainforest of Southeast Alaska contains abundant live trees, snags, and fallen logs in a variety of sizes. The extensive karst formations in Southeast Alaska also provide numerous caves where hibernating bats have been observed and collected in winter. Roosting habits unknown in Alaska. Elsewhere, day roosts include rock crevices, tree cavities, tree bark, and buildings. Night roosts include caves and mine shafts (Barbour and Davis 1969, Nagorsen and Brigham 1993, Parker et al. 1997).
